GLSA-201701-40 : xdelta: User-assisted execution of arbitrary code
Medium Nessus Plugin ID 96544
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201701-40 (xdelta: User-assisted execution of arbitrary code)
A buffer overflow can be triggered within xdelta when ran against a malicious input file.
A remote attacker could coerce the victim to run xdelta against a malicious input file. This may be leveraged by an attacker to crash xdelta and gain control of program execution.
There is no known workaround at this time.
SolutionAll xdelta users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-util/xdelta-3.0.10'
